Questions:

(1) Am I missing anything?
(2) Is there anthing I did that would cause system instability?
(3) The GameBar Presence Writer and X-box Monitoring are fairly obscure tweaks. Are they still applicable?

Thanks!

HKEY_CURRENT_USER\System\GameConfigStore -> GameDVR_Enabled DWORD = 0 (off)

Turn off Game Mode Notifications, turn off Game mode, turn off Game Bar tips, and disable Open Xbox Game Bar using Xbox button on Game Controller (respectively):
HKEY_CURRENT_USER\Software\Microsoft\GameBar -> ShowGameModeNotifications DWORD = 0 (off)
-> AutoGameModeEnabled DWORD = 0 (off)
-> ShowStartupPanel DWORD = 0 (off)
-> UseNexusForGameBarEnabled DWORD = 0 (off)

Turn off GameBarPresence Writer
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsRuntime\ActivatableClassId\Windows.Gaming.GameBar.PresenceServer.Internal.PresenceWriter -> ActivationType dword = 0 (off)

Disable Xbox Game Monitoring

@Karlie Weng

Would it be easier to rename xbgmsvc.dll to something like xbgmsvc.dll.old rather than delete?
